Hi Valdis,
The canonical place to check would be the git tree for drivers/staging:
https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/
In general, if there's other people doing active development, they'll show up in 'git log -- drivers/staging/pi433/'
And there's only one person doing a lot of patching - and most of those are coding style - though he did do a locking fix in April.
What particular issue are you looking at?
For example the TODO entry at line 876: If pi433_release() is called while pi433_ioctl() is executing between lines 879 and 880, we might perform a NULL pointer dereference, right ? Regards, Hugo -- Hugo Lefeuvre (hle) | www.owl.eu.com 4096/ 9C4F C8BF A4B0 8FC5 48EB 56B8 1962 765B B9A8 BACA
